As of this writing (April 2021), they only accept cash. This was something that I suspected and was wondering about as I entered and it was confirmed by a sign next to the cash register ("NUR BAR"). It would have been a bummer if I were unprepared after standing in line.
They are currently following Covid protocols. Only six people are allowed inside at a time. Because it's popular on a Saturday afternoon, the line is out the door. The wait didn't feel long, though. They do a good job of moving things along.
The menu is not super extensive but they have the basics. I chose Taro Milchtee (Taro milk tea). They have have the add ins on the menu but at the register, they have an official list of what they have that day.
Your receipt has a number. They call both the number and your order when it's ready.
Of course there is no seating inside due to Covid. You have to take your drink out.
